Supply Chain Game Analysis Considers Vendor Service And Retailer Return

In the 21 st century,most manufacturing companies to product definition from simple tangible products,extended to product-based value-added services,that is,product service.Vendors to provide products and services to a certain extent affected the needs of products and profits,while retailers in the choice of vendors will refer to the level of product service and purchase price and other factors,the development of sales strategy,of course,retailers will face return to bring the loss of profits,how to coordinate with the vendor return costs,to achieve the best profits to become a business and scholars of the hot spots.This paper analyzes the service level of the vendor and the retailer's pricing and return strategy,and considers a vendor and a retailer's secondary service supply chain to study the problem of the distribution of benefits of its vendor and retailer.In this paper,we first summarize the theory of service supply chain,reverse supply chain pricing model,Nash equilibrium and Stankelberg equilibrium.Secondly,we study the supply of products and services by vendors,retailers return to vendors,and retailers to develop corresponding products retail prices,in a vendor and a retailer's supply chain under the premise of considering the service level,product pricing and return of these three factors,the establishment of vendor services and retailers pricing and return of the profit mathematical model,the use of Nash equilibrium and Stankelberg equilibrium theory is solved.Finally,the feasibility and validity of the model and algorithm and the correctness and validity of the inference are verified by an example.The study shows that under the premise that the profit of the vendor and the retailer is the best,the obtained vendor divides the optimal proportion of the return logistics cost,the optimal service level of the vendor and the optimal pricing of the retailer,the Nash equilibrium The optimal solution is unique,and the vendor does not share the cost of return logistics.In the Stankelberg equilibrium,the proportion of the vendors in the model to share the return logistics costs depends on the whole sale price.
